Add WASIp3 support (#3272)

* update Wasmtime dep to `release-37.0.0`

v37.0.0 will be released later this month; this is a draft based on the Git
branch for that release so we're ready when the release happens.

Closes #3270

* update Rust version to 1.87

This is required by Wasmtime 37.

* restore accidentally-removed `wasi::io::error::add_to_linker` call

* Add WASIp3 support

This adds wasi:{cli,clocks,filesystem,http,random,sockets}@0.3.0-rc-2025-08-15
support, including inbound and outbound HTTP requests.

I've smoke tested this manually with a few WASIp3 components and plan to port
over some or all of the existing WASIp2 tests.

TODO:
  - Port wasi:[email protected] tests
  - Add `Instrument::in_current_span` calls where necessary (e.g. in wasip3.rs)
  - Update to next release candidate once the `release-37.0.0` branch supports it
  - Switch to the final 37.0.0 release once it's available

* add todo comments and change more bails to unreachables

* add WASIp3 port of `wasi-http-streaming` test

This required adding the 0.3.0-rc-2025-08-15 WIT files to the tree so
`wit-bindgen` could use them.

I've also addressed Till's feedback to match only the exact 0.3.0 RC we support
when looking for the `wasi:http/handler` export.

Finally, this includes a temporary workaround for
bytecodealliance/wasmtime#11703, which was uncovered
by the streaming test added in this commit.
